Due to the lightweight compaction procedure, LWC-store reduces the write amplification by a factor of up to 5× compared to the popular LevelDB key-value store. Below are examples of key-value stores. I am looking for a lightweight, reliable and fast key/value database for storing binary data. Many KV stores use flash devices for meeting their performance needs. An interesting point to note is that Mobile CouchBase is primarily written in Erlang, so porting any existing key/value stores is not dependant on their native language being C or C++. FIGURE 1. In this paper, we present DELI, a DEferred Lightweight Indexing scheme on the log-structured key-value stores. Welcome pickleDB is a lightweight and simple key-value store. Keys and values are just arbitrarily-sized byte streams. However, it performs file rewrites at the disk level, which causes write amplification.

RocksDB uses a log structured database engine, written entirely in C++, for maximum performance. Thanks for contributing an answer to Software Recommendations Stack Exchange! Not key/value, but Mobile CouchBase (CouchDB) supports iOS and apps using it have been approved for the App Store. simple numeric data - int/float values, nothing more, no JSON, blobs and so on, full copy of dataset on every node or automated failure tolerance, automatic adding/removing of hosts with no need to reconfigure application, small dataset - only a few megabytes of shared data, node traffic is load balanced with user-to-node sticking, so only one node at once will - change data related to users that are sticked to that node. LiteDB is a serverless database delivered in a single small DLL (< 450kb) fully … Other key-value databases only store data in memory and are generally known as key-value cache databases. This will only change on node failure, but constraint of one master for a set of keys will be keeped, so many readers, one master for own small dataset, multiple small VM instances will be used, so it should be lightweight in terms of required memory, automated operation - configure once and forget. Many KV stores use flash devices for meeting their per- formance needs. I have benchmarks where Hive ist about 2-3x the speed of Sembast. A player's character has spent their childhood in a brothel and it is bothering me.
